What is the simplified form of the quantity 4 x squared minus 25 over the quantity 2x minus 5 ?

Alenkasestr [34]

Answer:

B. 2x + 5, with the restriction x ≠ five over 2

Step-by-step explanation:

The given expression is the difference of squares, so factors as ...

the product of the quantity 2x plus 5 and the quantity 2x minus 5 over the quantity 2x minus 5

You will note that the numerator and denominator have a common factor:

the quantity 2x minus 5

Factoring that out gives ...

2x + 5, with the restriction x ≠ five over 2 (x is restricted from being a value that makes the denominator zero.)

Shazia sells 25x^2+5x+5 flowers in one day. If she sells the same number of flowers each day for rs 5x each , how much money wil

Mumz [18]

Answer:

$Total = 625x^3 + 125x^2 + 125x$

Step-by-step explanation:

Given

$Flowers = 25x^2 + 5x + 5$

$Unit\ price = 5x$

Required

The total price for 5 days

First, calculate the total for a day.

$1\ day = Unit\ price * Flowers$

$1\ day = 5x * (25x^2 + 5x + 5)$

Open bracket

$1\ day = 125x^3 + 25x^2 + 25x$

For 5 days, the total will be.

Total = days * sales of a day

So, we have:

$Total = 5 * [ 125x^3 + 25x^2 + 25x]$

$Total = 625x^3 + 125x^2 + 125x$

What I the slope of the equation of the line below.

Goshia [24]

Answer:

<h2>the slope m = 3</h2>

Step-by-step explanation:

Look at the picture.

The formula of a slope:

$m=\dfrac{y_2-y_1}{x_2-x_1}$

From the graph we have the points (0, 4) and (-2, -2). Substitute:

$m=\dfrac{-2-4}{-2-0}=\dfrac{-6}{-2}=3$
